The two most common vices are Renzetti (rotary) and Regal. If you live near a fly shop such as Orvis, take a hook and bobbin to the shop and try them out.
RCFetter dont forget the Peak's are in that common category as well. Actually I would considered the most popular brands to be the Renzetti, Regal and the Peak.
There's a lot of help out there. Do a web search on "Fly tying vise". You will see reviews. I found one that rated the Peak highly and that's what I got. I like it.
